IMPROVEMENT IN PUMPS OPERATED BY SPRINGS OR WEIGHTS.

Specification forming part of Letters Patent No. 197,854, dated December 4, 1877; application filed July 30, 1877.

To all whom it may concern:

Be it known that I, AROHIBALD L. HUNSA- KER, of Hunsaker, county of Tulare, and State of California, have invented Improvements in Pumps; and I do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanyin g drawing.

My inventionrelates to the employment of a T-shaped lever for operating two pumps by a train of gears which receive'their power from a spring or weight.

Referring to the accompanying drawing, in which the figure is a perspective view, let A represent a frame, inside of which a train of gears is mounted. Power for driving the train of gears is. furnished by a spring, B, in the usual manner of applying spring-power. One end of the shaft 0, upon which the last gear-wheel of the train is secured, projects outside of the frame A, and on its extremity is secured a crank-wheel, E. F is a T-shaped lever, which is attached to the frame A, so that its fulcrum is at some point between the middle of its vertical leg or lever O and the projecting arms at its upper end. A pump, L,

is located directly below the extremity of each of the armsG H, and the piston-rod of each Having thus described my invention, what I claim, and desire to secure by Letters Patent is 'Ilhe T-shaped lever attached to the frame A,

' as described, and having the lower end of its vertical arm 0 provided with a slot, P, with which the crank-pin J engages, and having the piston-rod of a pump, L, attached to each of its horizontal arms, the several parts relatively arranged with each other, and in connection with a train of gears and spring-power, sub stantially as above described.

In witness whereof I have hereunto set my hand and seal.
